Sulfur Recycling Catalysts – Claus Catalyst
Application:
Gas and crude oil refining companies use it to convert hydrogen sulfide (H2S) to sulfur (S).
Product Introduction:
Sulfur recovery catalyst or SRU is used in the famous Clause process in gas and crude oil refining companies to convert hydrogen sulfide (H2S) to sulfur (S).
16H2S + 8SO2 —< 3S8 + 16H2O
There are different types of sulfur recovery catalysts, which can be divided into the following three categories:
1. Aluminum-based catalysts
2. Oxygen scavenger catalysts (treated with iron)
3. Titanium oxide catalysts: It has multiple uses and is used to hydrolyze CS2
and COS compounds in feed.
The complete production process of this catalyst includes the following steps:
1. Crystal formation (nucleation) from alumina powder or titanium oxide
2. Shaping operations
3. Heat treatment (drying and calcination)
